Large animals with ailing livers can grow new organ in lymph nodes from their own hepatocytes

Hepatocytes -- the chief functional cells of the liver -- are natural regenerators, and the lymph nodes serve as a nurturing place where they can multiply.

Researchers develop 3D imaging technique to visualize damaged lung tissue after severe COVID-19

Physicists at the University of Göttingen, together with pathologists and lung specialists at the Medical University of Hannover, have developed a three-dimensional imaging technique that enables high resolution and three-dimensional representation of damaged lung tissue following severe Covid-19.

COVID-19 causes significant dilation of lung blood vessels, indicates study

A new pilot study from the Icahn School of Medicine at Mount Sinai suggests that COVID-19 is causing significant dilation of the blood vessels of the lung, specifically the capillaries.

Immunothrombotic dysregulation is key marker of disease severity in COVID-19

In severe cases of COVID-19, the infection can lead to obstruction of the blood vessels in the lung, heart and kidneys. Ludwig-Maximilians-Universitaet (LMU) in Munich researchers have now shown that activated immune cells and blood platelets play a major role in these pathologies.

Neutrolis announces development of first-in-class therapy to target NETs in COVID-19 patients

Neutrolis, a biotechnology company developing therapeutics that target neutrophils, the most abundant immune cells in the body, today announced the development of NTR-441, a first-in-class DNASE1L3 enzyme analog that has the potential to rapidly and systemically clear neutrophil extracellular traps for severe cases of COVID-19.

Common hypertension drugs do not increase risk of severe, fatal COVID-19 infection

A new Northwestern Medicine study in mice found a widely used class of drugs to treat patients with hypertension, cardiovascular disease and diabetic kidney disease - many of whom are elderly -- does not increase the risk of developing a severe and potentially fatal COVID-19 infection, as previously feared.

Obesity and metabolic syndrome increase risk for severe influenza, COVID-19

Metabolic syndrome increases the risk of severe disease from viral infection, according to a review of the literature performed by a team of researchers from St. Jude Graduate School of Biomedical Sciences and the University of Tennessee Health Science Center, both in Memphis.

PrecisionLife scientists identify 68 genes linked to severe COVID-19 risk

PrecisionLife’s unique AI platform has found 68 genes associated with risk of developing severe COVID-19 after analysis of the genomes of 929 patients from the UK Biobank who had a severe response to SARS-CoV-2.

Repurposing immunosuppressants to manage COVID-19

It might seem paradoxical to suggest immunosuppression could play a role in managing COVID-19. The seemingly logical therapeutic option for this disease would be an antiviral.

Severity of COVID-19 linked to heparanase activity and heparan sulfate levels

Researchers at Radboud University Medical Center in the Netherlands reported an increase of heparanase activity and heparan sulfate levels in the plasma of patients with coronavirus disease (COVID-19), which was also associated with the severity of the condition – suggesting, in turn, potential treatment utility of low molecular weight heparins. The paper is currently available on the medRxiv* preprint server.

Researchers receive federal funding to rapidly repurpose FDA-approved drugs for COVID-19

Researchers at the University of Maryland School of Medicine will be partnering on an agreement funded by the federal government's Defense Advanced Research Projects Agency (DARPA) to rapidly test hundreds of drugs, approved and marketed for other conditions, to see whether any can be repurposed to prevent or treat COVID-19.

Oncotarget: mi R-151a overexpression enhances tumor-associated angiogenesis

Volume 11, Issue 23 of @Oncotarget reported that the authors have previously established that mi R-151a functions as an onco-mi R in non-small cell lung cancer cells by inducing partial EMT and enhancing tumor growth.

Study provides molecular explanation to a longstanding mystery in viral oncology

The oncogenic herpesvirus (HHV8 or KSHV) causes a cancer known as Kaposi's Sarcoma. An international team of scientists led by the University of Helsinki has discovered key factors that control the genome maintenance and replication of a virus responsible for lymphatic vascular cancer.
